Note:
(1) Flange insulation is not necessary between flange and
heat-sink, flange and resistor is separated by alumina
substrate.
(2) Resistance measurement shall be made at terminal foot
position.
(3) TCR of low resistance will be increased as
300ppm/0.02Ω, 200ppm/0.05Ω, 140ppm/0.1Ω and
80ppm/0.2Ω typically. Testing point is at 5.27mm from
bottom of molding of terminals.
(4) Test method is IEC60068-2-6, and specification is
sine sweep wave form, 100Hz-2000Hz, 10 cycles,
amplitude 0.75mm or 100m/s2, 90minutes. direction x-y
z, Amplitude 0.75mm will be applied under break point
Frequency (about 60Hz) and 100m/ s2 over break point
(5) Standard packaging is tape reel, a tape reel contains
500pcs. when small quantity, tube packaging will
be used, the tube is made by RoHS PS/PE which
contains 50pcs / tube.
